Cash Flow

Quick Definition

The movement of money into and out of a business, showing actual liquidity rather than accounting profit.


What is Cash Flow?

Cash flow measures the actual movement of money in and out of your business. Unlike revenue or profit, which are accounting concepts, cash flow shows what's really happening in your bank account.

A profitable company can run out of cash if customers pay slowly or inventory ties up capital. Cash flow tells the survival story that income statements don't.

Types of Cash Flow

Operating Cash Flow: Cash from core business operations. Investing Cash Flow: Cash spent on or received from investments and assets. Financing Cash Flow: Cash from or to investors and lenders. Free Cash Flow: Operating cash flow minus capital expenditures.

Why Cash Flow Matters

Cash is oxygen. You can survive losses but not running out of cash. Many profitable startups have died because they couldn't cover payroll while waiting for customer payments.

Investors scrutinize cash flow because it reveals business quality. Companies that convert profits to cash efficiently are more valuable than those with profit that never materializes as cash.

Formula

Net Cash Flow = Cash Inflows - Cash Outflows

Operating Cash Flow = Net Income + Non-Cash Expenses + Changes in Working Capital

Free Cash Flow = Operating Cash Flow - Capital Expenditures

Example

Monthly cash movements:

  • Cash from operations: +$50,000
  • Cash from investing (equipment): -$20,000
  • Cash from financing (loan payment): -$10,000

Net Cash Flow = $50K - $20K - $10K = +$20,000

Your cash position improved by $20K this month despite capital investments.
